Narrative:

I was on a training flight for an instrument proficiency check. The WX was VMC (severe clear, visibility unrestricted) and there were 3 VFR aircraft in the pattern at koto. ATC vectored us to the final approach course for the NDB 17 approach. The pattern was using runway 35 and that put us flying against the traffic flow. I saw traffic departing koto on runway 35, I instructed the pilot to turn right at pinck (OM) and reacquire the final approach course. This would give us sufficient spacing to continue the approach safely and not disturb the current VFR traffic at koto. We were in VMC, I felt it was my responsibility to see and avoid all traffic even though we were on a VFR flight plan. ATC had told us separation services were not available in the pattern. ATC was upset with my decision and proceeded to scold me on the air about pilot deviation. The flight safety was never in jeopardy and we completed the flight as planned.

Narrative: I WAS ON A TRAINING FLT FOR AN INSTRUMENT PROFICIENCY CHK. THE WX WAS VMC (SEVERE CLR, VISIBILITY UNRESTRICTED) AND THERE WERE 3 VFR ACFT IN THE PATTERN AT KOTO. ATC VECTORED US TO THE FINAL APCH COURSE FOR THE NDB 17 APCH. THE PATTERN WAS USING RWY 35 AND THAT PUT US FLYING AGAINST THE TFC FLOW. I SAW TFC DEPARTING KOTO ON RWY 35, I INSTRUCTED THE PLT TO TURN R AT PINCK (OM) AND REACQUIRE THE FINAL APCH COURSE. THIS WOULD GIVE US SUFFICIENT SPACING TO CONTINUE THE APCH SAFELY AND NOT DISTURB THE CURRENT VFR TFC AT KOTO. WE WERE IN VMC, I FELT IT WAS MY RESPONSIBILITY TO SEE AND AVOID ALL TFC EVEN THOUGH WE WERE ON A VFR FLT PLAN. ATC HAD TOLD US SEPARATION SERVICES WERE NOT AVAILABLE IN THE PATTERN. ATC WAS UPSET WITH MY DECISION AND PROCEEDED TO SCOLD ME ON THE AIR ABOUT PLT DEVIATION. THE FLT SAFETY WAS NEVER IN JEOPARDY AND WE COMPLETED THE FLT AS PLANNED.
